The wallswoftheseyertical channels andA thef insulating materlal arel v perforated to `receive-suitabl'e, tying; bolts 11 for securing the-cans" in series against displacement in thegouter:tank. As' seen' from the upper left-hand corner Lof Fig. 2..,thevbolts 11 are hollow'for a purpose hereinafter referred to, Aand it will also be lseen that a stripl yof suitable material` 11 is preferably placed between a `lbottom channell8,:=forming troughs for the I Y water tight joint mightbe employed. In.

the faces of the offsets 7 where they abut, to provide a water seal between the opposed channels formed by the cans and baiiie plates. The outer tank may also be provided; with vertical end blocks 12 of insulating material, against which the end channels 7 abut.

In the construction shown in Fig. 4 the cans are joined together by the integral walls 13 and 'a continuous channel 15 and 16 extending vertically of the end cans and joining a channel 17 lon itudinally along the bottom of the series o cans is filled flush with suitable insulating material.

In Fig. 5 the same arrangementy of inner ice cans is shown as is shown in Fig. 4, 14:and 14k1 showing suitable surfaces of insulating material extending along the vertical faces of the integral wall 13. In this view the insulating material 17a (Fig. 7) vis shown omitted from the bottom channel 17 in order to illustrate more clearly a perforated inlet pipe 18 having a plurality of upwardly directed nipples 19 disposed adjacent the vertical insulating surfaces of the walls 12.3. As shown in Fig. .7 the insulation 17 1s grooved out on its bottom, as at 20, to snuglyn fit over the pipe 18, and is also provided with apertures 21 to receive the nipples 19.

While I have shown the nipples disposed adjacent the walls 13 'it will also be understood that the pipe may be provided with other injection orifices if desired, but in ad dition to the object of always providing a continuous How or agitation of, raw water in the ice forming chambers the particular location of the nip les 19 accomplishes a further end in keeping the water more violent-ly agitated adjacent the surfaces 13 where it is desired thatthere be no possible ice formation. l

It will be seen from Figs. 5 and 6 that the raw water inlet pipe 18 is arranged in the bottom of the channel extending -longitudfinally along the bottom of the outer tank, but

where the single can construction is used, as shown in Flgs. 1 and 2, the arrangement would be such that after the single cans were assembled` and secured together the inlet pipe 18 would be secured along the outside bottom of the channels 8, 1n which event the pipe would be fitted with a socket or nipple coperating with a complementary element on the bottom of the tanks to form a water tight joint, or any other suitable this construction, of course, the inlet orifices could not be arranged yin the same position as shown in Fig. 5, as the insulating material 9 would prevent this, so that the inlet orifices would be arranged immediately adjacent this insulating material 9, 'as indicated 4at 19", Fig. 1.

22 designates an outlet for the raw water which is conducted by a suitable pipe, not

shown, toda receptacle in which it is either stored or led back again after filtratlon and further cooling to the inlet p ipe 18. In yop eration, therefore, it will be seen that the incoming brine being discharged'` in the space between the outer tank and the rst ice forminor can, and on both sides of the bottom dividing wall of insulating material,

the flow will be in the direction of the ar-A rows until the opposite end of the outer tank' is reached, when the overiow through the pipes 4. y

During the-formation of ice a central wall or zone of unfrozen water is maintained in each ice forming compartment, owing to the insulating material referred to and-the raw water] agitating means comprising the inlet pipe and jet orifices, and the ice forms from passes out opposite sides of each compartment towardl this wall of unfrozen water.-

Any suitable means may be provided for drawing offthe water, if desired, after the ice blocks have been formed, and communiaoy cationis had between the several ice4 formy mg cans of the series, Figs. 1 and 2, from the fact that the bolts 11 are open-ended.\

For instance the inlet pipe 18 may be provided with a suitable cock for allowin the' water in the tank to be drained' t erethrough. Y.

What I claim is 1. In an apparatus for manufacturing ice,

an outer tank provided with opposed alining baffle plates having a substantial space between Vtheir opposed edges,l in combinat1on witha plurality of ice forming chambers the adjacent walls of which are spaced apart and straddle said bale plates, and means forcirculatingl a cooling medium in said outer tank, substantially as described.

2. In an apparatus for manufacturing ice,

4. In an apparatus for manufacturing ice, the combination of an outer tank rovided ice across said channels, substanwith opposed alining baile plates aving a i substantial space between their edges, a plurality of icel forming receptacles having their side walls spaced apart and straddlmg iny said vbaile plates, means for circulating a forming receptacles in aplane passing between said baiiie plates, and means for conducting off saidraw water at a predetermined level, substantially as described.

5. In an apparatus for manufacturing ice,

`the combination of an outer tank provided with opposed alining baille plates having a substantlal space between their edges, a plurality of ice fo-rming receptacles having their sidewalls spaced apart and straddling said bafiie plates, means for circulating 'a cooling medium through said brine tank,

and means for introducing raw water into said receptacles at a position between the space formed by the opposed edges of said baiie plates, and means for conducting @if said raw water at a predetermined level, substantially as described.

6.v In an apparatus for manufacturing ice,

` the combination of a brine tank, an inner tank comprising a plurality lof ice forming receptacles having their adjoining side walls spaced apart to form hollow partitions having opposed spaced inner faces forming a 'passage longitudinally of said inner tank,

- 3.0.means for injecting raw water in said longitudinal passage, and means for conducting oi" said raw water at a predetermined level, substantially as described.

7. In an apparatus for manufacturing ice,

tially as described.

the' combination of a brine tank, an inner tank comprising a plurality of ice forming receptacles having their adjoining side walls spaced'apart to form hollow partitions having opposed spaced inner faces forming a passage longitudinally of said inner tank# facing's of insulation for. said inner faces, 40

means for injecting raw water in said longitudinal passage between the opposed inner faces, and means fof conducting `o`f said raw water at a predetermined level, substan- 8. In an'apparatus for manufacturing ice, the combination of a brine tank, an inner tank provided with inwardly projecting hollow partitions with opposed inner end walls spaced apart and provided with a -bottom 5( channel below the space formed by said spaced end walls, a raw water inlet pipe extending along said channel, insulating ma terial in said 'channel and covering said pipe, orifices being provided in said pipe and said insulating material discharging in the zone abovesaid channel, and means for con# a ducting oi the raw water at a predetermined level, substantially as described.
